C#

var pageInfo = pdfViewer.GetPageInfo(1);
var cropBox = pageInfo.CropBox;

PdfPoint stickyNotePoint = new PdfPoint(cropBox.Right - 20, cropBox.Top - 20);

var points = new[] { new PointF((float)stickyNotePoint.X, (float)stickyNotePoint.Y) };

PdfDocumentPosition stickyNotePosition = new PdfDocumentPosition(1, new PdfPoint(points[0].X, points[0].Y));
pdfViewer.AddStickyNote(stickyNotePosition, "Note", Color.Yellow);

VB.NET

Dim pageInfo = pdfViewer.GetPageInfo(1)
Dim cropBox = pageInfo.CropBox

Dim stickyNotePoint As New PdfPoint(cropBox.Right - 20, cropBox.Top - 20)

Dim points = { New PointF(CSng(stickyNotePoint.X), CSng(stickyNotePoint.Y)) }

Dim stickyNotePosition As New PdfDocumentPosition(1, New PdfPoint(points(0).X, points(0).Y))
pdfViewer.AddStickyNote(stickyNotePosition, "Note", Color.Yellow)
